Hurricane Sandy Data Highlight
An integral part of the National Science Foundation's Earthscope initiative is the USArray and in particular, the Transportable Array. The TA consists of 400 broadband seismic stations deployed on a uniform grid with ~70 km station spacing. The TA has been rolling across the US since 2004 from West to East with stations occupying sites for 2 years at a time. In 2011 infrasound sensors measuring atmospheric pressure were installed at all new sites. This movie highlights the effect of Hurricane Sandy on ground motion and atmospheric pressure at TA as well as other stations across North America whose data are available through IRIS web services.
